NON-VOLATILE MEMORY DEVICE AND HOST DEVICE CONFIGURED TO COMMUNICATION WITH THE SAME

摘要

A non-volatile memory device and a non-volatile memory host device are configured to communicate with the non-volatile memory device. The speed at which the non-volatile memory device responds to a request for accessing user data from the host device may be increased. The non-volatile memory device may transmit logical-physical address mapping information regarding user data to the host device and may receive a request and logical-physical address mapping information from the host device. The host device may receive and store the logical-physical address mapping information from the non-volatile memory device and may transmit the request for accessing the user data and stored mapping information to the non-volatile memory device.
